r The principal object of my present invention is that of providing material improvements both in the functioning of the device as a door catch and lifter, as well as providing a simple, efficient,

and convenient door lock in combination with the catch and lifter.

Another material advantage of the instant invention is in the manner of installation of same in respect to both the door opening and the door. I

Other objects and advantages of the invention willappear in the followingdescription thereof.

Referring now to the accompanying drawing, forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is an elevation of the door catch as mounted upon the door and in its normally closed position in respect to the door opening.

Figure 2 is a section on the line 22, Figure 1, showing portions of the device in elevation.

Figure 3 is a perspective view of the lock attachment which may be operated in conjunction with the combined lifter and catch.

Figure 4 is a somewhat enlarged perspective view of the lower end of the door catch, designated for cooperation with the lock.

Figure 5 is a somewhat reduced perspective view of the novelform of trigger.

The numeral I represents a screen, storm, or other door, as the case may be, for operation within a common door opening, that portion of the door illustrated in the drawing being the free upper edge thereof and which in this instance is designed to engage the edge of the stop 2 within the door jamb 3 of the door.

The catch here illustrated differs only in minor details from that shown in my former application, supra, and it is not deemed essential to describe same in detail, other than to clearly point out these differences, and which will be done hereinafter.

As in my former application, 4 represents the base plate of the catch, which'is substantially U-snaped in cross-section and. having the out- Wardly extending somewhat triangularly shaped side walls 5 at the upper extremities of which,

as at K, is the through pin, supporting exter-- pally of said side walls 5 the jaw-like housing 1, which oscillates back and forth on said pin when engaged by the cooperating means upon the door as the latter is opened or closed. The lower outer corners of the side walls 5 are provided with circular openings II in which is pivotally' supported the inner end of the trigger member 9, it having upturned side flange-like rearwardly extending members 38 formed integral therewith and each of which flanges carries an inwardly propecting arcuate lug 3! which bears against the circumferential edges oi"v the openings .H, thus providing a substantial and durable bearing for said pivotal support of the trigger when assembled.

It will be'noted that a slot or gap 32 is formed in the outer wall of each opening II for convenient assembly of these cooperating parts as the side flanges of the trigger are externally of the side walls of the base plate 4, and the housing 1 is externally of the trigger when the device is fully assembled. The free end of this trigger extends through a suitable opening 283 in the bottom of the housing 1 for cooperative engagement with the finger projection l4 thereof when the latter engages the roller on the fixed spindle l6. Intermediate of the side members 3!] of the trigger and the body portion thereof if formed a hole I2 for hooked engagement with the upper end of the contractile helical spring i3, theopposite end of this spring being hooked about the pin 6 which pivotally supports the housing 1, pre-- viously described. The lower end of the housing 1 is provided upon its innermost edge with a finger-like projection M which cooperates with the trigger '9 in gripping or releasing the roller I5 carried upon the spindle l6 secured to the face of the stop 2 and adjacent the edge thereof. It will be noted by this construction that when the housing I is in its outermost extreme position the axial alignment of the spring, i3 is slightly at an angle to the line of draft, which would hold the housing normally biased toward its open position ready for the reception of the cooperative attachment carried by the stop, whereas when impinging such attachment on the stop with any degree of force as when the door is swung shut, the housing will be drawn slightly toward the door together with the otherwise free end of the spring beyond that inactive line of stress, and bias the housing toward closed position, thus carrying the door to like position.

vIt will be noted here that while the general construction of the cooperative parts of the catch are similar to that shown in my former application referred.- to, the catch itself is turned end for end, or upside down, and mounted upon the door instead of on the door trim, and that in this of the stop 2, thus providing convenient means as a gage. for horizontal placement of the pin l6;

Another novel feature of the instant case is that the free end of the trigger 9 extending beyond the housing I is formed with an oifset or hump indicated at 22, the same acting as a stop in engaging the lower end of the housing l as clearly illustrated in Figure 2 of the drawing thus preventing abnormal wear within the opening 20 in the end of the housing.

Another novel feature of the instant case is that of the lower extremity of the base plate 4 .being ofiset outwardly asat 23 approximately the thickness of the metal of which it is-made, and in which offset portion is installed the circular rubber button 24- forabutting contact with the finger of the housing to lessen or cushion the sound of the action of the catch.

Now this lower extremity of the base plate 4 is offset for the reception of the upper forkedend of the escutcheon plate 25, the tines of which forked portion will readily straddle the inner projectingend of the button and be housed underneath the projection 23 when slid upwardly beneath same, and a holding screw, not shown, is

installed within the hole 2% in the lower extremity of the escutcheon plate. This plate is provided with a ,rectangularly shaped outwardly stepped portion 21 intermediate of its ends and upon which is pivotally mounted as at 28 the thumb button 29 foradjustment to or from engagement with the free end of the finger ['4 when the latter is in closed position against the button 24, whereby to act asa lock for the. door, it being understood that when the escutcheon plate 25 is shoved up into place under the stepped portion 23 of the base 4, the extending portion 21 thereof will 1 be in the same-plane with the finger [4 to provide for such convenient engagement. By this provision of separable locking means it is, obvious that tarian properties of the catch are materially augmented.

It is apparent that the same convenient ad justment of the device is provided for the lifting of the door during the closing. process by the proper positioning of the pin l6 that occurs in K my former application, but in this instance the pin is upon the stop of the jamb insteadfoi on the door as in my former application.

Having thus described my invention, what I 15'. claimand desire to secure by Letters Patent, is: v i

l. A door catch comprising a channel shap'edbracketiportion, the side walls of which are provided, with circular openings therein, a trigger having arcuate lugs thereon for pivotal engagement within the circular openings of said bracket portion, a'housing pivoted adjacent one end to said bracket portion,and'means for biasing the trigger and housing toward the limit of its move: ment in either direction. 1

' 2. A door catch comprising a channel shaped bracket portion having circular openings through the side walls thereof, a trigger having laterally extending surfaces adapted to extend within and bear'against the edges of saidopenin'gs for pivotal engagement therewith, a housing pivoted adjacentone end to said bracket portion, and a spring secured at one end to said bracket portion and at the other end to said trigger for biasing the trigger and housing toward the limit of its movementinzone direction.

3. In a door catch having a pair of cooperative members each having a pair of spaced parallel walls, one of said members having axially aligned substantially circular openings in the spaced walls thereof, and the other of said members having laterally extending-lugs in the spaced walls thereof and-adapted to extend within and bear against the edges or said circular openings to form a pivotal joint between said cooperative members- HIRAM B.
